.DISCUSSION...
Lets begin by discussing the celestial elephant in the room. With
the final full forecast package before the onset of the solar
eclipse (which will begin at approximately 11:50 AM this morning)
viewing conditions are expected to be generally favorable.
Scattered cumulus clouds will partially obscure the sky, but
should not be widespread enough to cover the entire duration of
the eclipse (which will last nearly two hours from start to
finish). An isolated thunderstorm or two cannot be completely
ruled out, but a quick drive of 10 or 20 miles will likely put you
back under a viewable sky. Of course with mostly clear skies the
sun will still be doing what it does and heat indices will be in
the 100-105 range during the eclipse. Be sure to stay hydrated
while viewing.

A TUTT low will continue to gradually progress west across the
gulf of Mexico over the next couple of days which will serve to
enhance rain chances somewhat tomorrow into Wednesday before
washing out along the east Texas coast. However, rain chances
will remain above normal through the end of the week as the region
will be squeezed between a digging upper level trough across the
eastern US and the remnants (or regeneration) of Harvey in the bay
of Campeche. While the frontal system associated with the trough
is not progged to make it through the area, the higher rain
chances (and cloud cover) will result in temperatures a few
degrees cooler for the latter half of this week into early next
week.

.MARINE...
High pressure at the surface will keep winds generally light out
of the south or southeast through the week. Rain chances will
increase beginning Tuesday through the end of the week as a
combination of a stalled frontal system to the north and abundant
moisture from the remnants of Harvey in the bay of Campeche will
result in numerous showers and thunderstorms.
